Doctors Best Gluosamine Chondroitin MSM

Glucosamine/Chondroitin/MSM contains pure glucosamine sulfate, as confirmed by HPLC testing. Glucosamine sulfate is extracted from chitin, a long-chain polymer consisting of many glucosamine molecules linked together. Chitin forms structural frameworks in many living things, including aquatic crustaceans such as lobsters, crabs, and shrimp. In our formula, the glucosamine is purified and then sulfated and stabilized with potassium chloride.

Note: Glucosamine sulfate is derived from the shells of oceangrown shellfish. It is processed to remove all residues of protein and impurities, yielding pure glucosamine sulfate as the final material.

Glucosamine/Chondroitin/MSM contains chondroitin sulfate with a purity of 90 percent or greater. Quality assurance testing is performed using two sophisticated laboratory analysis methods: high-performance liquid chromatography (HPLC), and Cetyl Pyridinium Chloride (CPC) Titration. Glucosamine/Chondroitin/MSM contains pure Lignisul^® MSM (methylsulfonylmethane), a natural-source MSM derived from trees. A biological compound that occurs in the human body and in some foods, MSM is an excellent dietary source of bioavailable organic sulfur.
The MSM Story-One of Nature's Primary Sources of Organic Dietary Sulfur!

The human body requires a continuous supply of usable sulfur, and MSM is one of the primary organic sulfur-containing molecules for use by living organisms. From life's earliest beginnings, primitive marine organisms (blue-green algae and phytoplankton) have absorbed inorganic sulfur from ocean waters and produced organic sulfur molecules, primarily dimethyl sulfonium salts. These salts are released back into the sea, where they are converted to dimethyl sulfide, which readily evaporates, ending up in the upper atmosphere. Dimethyl sulfide is then oxidized by UV light, forming DMSO and MSM. The two compounds are delivered to land masses in rain water, and absorbed by plants. MSM is a stable end product of this process, serving as a primary source of sulfur in the food chain.
